Suppose that a solution is tested for NO2 ion by adding 3M H2SO4 and heating, repeating this process until no further reaction o

ccurs. This solution
is then analyzed for NO3 ion by adding FeSO4 solution and more H2SO4, heating the test tube and its contents. The NO3 ion reaction is positive. In this case, is it accurate to state that NO3 ion was present in the original solution? Briefly explain. Write appropriate equations to support your answer.

Answer:

The correct equation will be "[Fe(H2O)5]²⁺ + NO → Fe(H2O)5NO]²+ (brown ring) ".

Explanation:

For NO₂, the addition of H₂SO₄ forms HNO₂ comprising NO gas as well as HNO₂, the equation will be:

⇒  NO₂⁻ + 2H⁺ →  HNO2

⇒  HNO₂ + H₂O + H⁺  →  HNO₃ + NO

For NO₃⁻,

NO₃⁻, Fe₂+ oxidized to Fe₃ + then releases NO gas in the existence of H₂SO₄

⇒  3Fe₂⁺ + 4H⁺ + NO₃⁻  →  3Fe₃⁺ + NO + 2H₂O

Brown ring forming establishes NO3- presence in the initial test sample,

⇒  [Fe(H2O)5]²⁺ + NO  →  Fe(H2O)5NO]²+ (brown ring)

What is the relationship between the Kuiper Belt and the status of Pluto today?
Xelga [282]

Pluto is a dwarf planet, but one of the largest known members, in the Kuiper belt.

The Kuiper Belt extends between 30 AU and 55 AU from the Sun

(1 AU = 1.5 × 10^8 km = distance from Earth to Sun).

Pluto's orbit is highly elliptical. It ranges from 30 AU to 50 AU. When Pluto is closest to the Sun, it is inside the orbit of Neptune (30 AU).

Astronomers class Pluto as a <em>resonant Kuiper belt object</em> (KBO). Because it gets so close to Neptune, its orbit is in <em>resonance</em> with that of Neptune. Pluto makes two orbits for every three of Neptune.

Which of the following would indicate that a chemical change might be occurring
Murljashka [212]

Explanation:

During a chemical change, a new kind of matter is formed. Examples are combustion, rusting of iron, precipitation and souring of milk.

Here are some of the properties of chemical change:

  • They are not easily reversible
  • It leads to the production of new kinds of matter.
  • It involves change in mass.
  • It requires a considerable amount of energy.
